￭ Control panel to drive cable
Use EIA-485 with male RJ-45 connector, cable type Cat 5e or better. The maximum permitted
length of the cable is 100 m (328 ft).
Routing the cables
￭ General guidelines – IEC
• Route the motor cable away from other cables. Motor cables of several drives can be
run in parallel installed next to each other.
• Install the motor cable, input power cable and control cables on separate trays.
• Avoid long parallel runs of motor cables with other cables.
• Where control cables must cross power cables, make sure they are arranged at an
angle as near to 90 degrees as possible.
• Do not run extra cables through the drive.
• Make sure that the cable trays have good electrical bonding to each other and to the
grounding electrodes. Aluminum tray systems can be used to improve local equalizing
of potential.
This figure illustrates the cable routing guidelines with an example drive.
Note: When motor cable is symmetrical and shielded and it has short parallel runs with
other cables (< 1.5 m / 5 ft), distances between the motor cable and other cables can be
reduced by half.
